This is the error message. I realize I'm getting a different error from the one I expected to get, but it still illustrates the problem.

Message: Error rendering screen component://example/widget/example/PortletScreens.xml#PortletErrorExample2: org.ofbiz.entity.transaction.GenericTransactionException: The current transaction is marked for rollback, not beginning a new transaction and aborting current operation; the rollbackOnly was caused by: Error in Service [exampleErrorService]: You must be logged in to complete the [] process. (The current transaction is marked for rollback, not beginning a new transaction and aborting current operation; the rollbackOnly was caused by: Error in Service [exampleErrorService]: You must be logged in to complete the [] process.)

If I add [ userLogin : userLogin ] to the service call, I get the expected error message, but the same result on the portal page.
